The quality of TN mattresses dropped substantially. I don't know why, but the corners no longer lay flat and they have cut corners elsewhere such as in the cover of the mattress. I currently own 4...I don't think we'll be buying more when these wear out in a few years. The degredation of quality is very frustrating.
This is our first foam mattress and we are very satisfied. I am a side sleeper and after the first couple of nights, I found my hips no longer hurt when I got up in the morning. Our only issue was the edges were soft and lacked support the first week but have since firmed up. We have been using for a month now and we are very happy with our choice.
Our first memory foam mattress so we went with the least expensive model. WHAT A JOY! No break in period. Perfect sleeping! Are actually thinking of upgrading prior to our 101 day expiration although I don't know why we would want to!
